Enhanced bone regeneration and formation around implants using guided bone regeneration

Journal of Biomedical Materials Research, 1998
This study investigated the use of a prototype expanded polytetrafluoroethylene membrane attached to bone with butyl-cyanoacrylate, in facilitating guided bone regeneration into bone defects and around titanium screws in rabbit femora. Two experimental models were used to assess bone growth.

Bone regeneration after radicular cyst removal with and without guided bone regeneration

International Journal of Oral and Maxillofacial Surgery, 1998
In order to determine the degree of bone regeneration after removal of radicular cysts using guided bone regeneration (GBR), a prospective, controlled and randomized clinical study was performed. Thirty patients with radicular cysts were divided into three groups.

Volumetric Changes Following Lateral Guided Bone Regeneration

The International Journal of Oral & Maxillofacial Implants, 2020
Resorbable membranes are well described and employed for horizontal guided bone regeneration (GBR). However, the currently available literature does not provide information on the bone volumetric changes during the healing that follows GBR procedures and dental implant placement.

[Guided bone regeneration: general survey].

Revue belge de medecine dentaire, 2009
The principle of 'guided bone regeneration' was first described in 1988 on the basis of animal-experimental data. Six weeks after transmandibular defects had been created and protected by non-resorbable teflonmembranes, complete bone regeneration was found.

Horizontal bone augmentation by means of guided bone regeneration

Periodontology 2000, 2014
AbstractThe development of bone augmentation procedures has allowed placement of dental implants into jaw bone areas lacking an amount of bone sufficient for standard implant placement. Thus, the indications for implants have broadened to include jaw regions with bone defects and those with a bone anatomy that is unfavorable for implant anchorage.

Prefabrication of Vascularized Bone Graft Using Guided Bone Regeneration

Tissue Engineering, 2004
This article describes the prefabrication of a vascularized bone graft composed of autologous particulate cancellous bone and marrow (PCBM), a vessel bundle, and a biodegradable membrane. The PCBM was placed around the saphenous vessel bundle of rats and rolled with a biodegradable membrane of L-lactide-epsilon-caprolactone copolymer to prepare the ...

Bioabsorbable laminated membranes for guided bone regeneration

Technology and Health Care, 2002
Guided tissue regeneration (GTR), or guided bone regeneration (GBR), can be considered as sub-areas of tissue engineering because the characteristics of newly forming tissue are commonly influenced as usual by the surgical intervention and more importantly by the morphology or topography of a biomaterial surface.

Bone regeneration using the principle of guided tissue regeneration

Journal of Clinical Periodontology, 1991
Abstract. The biological principle of “guided tissue regeneration” (GTR) was developed for regenerating periodontal tissues, lost as a result of periodontal disease. This principle was based on the hypothesis that non‐desirable types of tissue cells can be prevented from migrating into a wound by means of a membrane barrier and at the same time giving

Polymers in Guided Bone Regeneration

2022
In dental debilitating conditions, such as edentulism, the patient must have sufficient alveolar crest bone mass to guarantee the possibility of corrective interventions, such as implants. The decrease in bone tissue is caused by the body's natural reabsorption, which begins after tooth loss. Some surgical techniques could be used to solve this problem,

Histologic Analysis of Alveolar Bone Following Guided Bone Regeneration

Journal of Periodontology, 2004
Background: Questions on new bone quality following guided bone regeneration (GBR) with various graft materials and its importance in osseointegration have been raised. This study reports histologic analysis of bone sections from future implant sites at upper and lower jaws that were augmented with bovine porous bone mineral graft material plus a ...
